Cairo: An Egyptian Interior Ministry employee was killed in North Sinai, security officials said on Saturday, two days after jihadists aligned with the Islamic State group killed 30 people in the peninsula.

The 50-year-old, who worked for the road traffic department, was shot in the head in his home in the regional capital of El-Arish on Friday night, the officials said.

The Sinai has witnessed a surge in attacks against security forces claimed by jihadist groups since the July 2013 ouster of Islamist President Mohamed Morsi.

On Thursday, militants from Ansar Beit al-Maqdis -- which has pledged allegiance to IS in Iraq and Syria -- claimed a string of attacks, including a car bombing, that left at least 30 people dead.

Subsequent clashes between the Army and militants killed two children on Friday.
